Those Gi tops are excellent ! I purchased one last year for the summer months and it has been great. It fits well (it has shrunk a bit from numerous washings), and doesn't "stick" to your skin when you perspire like lightweight Karate Gi tops tend to do.

Indeed, I'm quite happy with mine. It absorbs sweat quite well without feeling disgusting, is roomy without being baggy, and moves smoothly and freely when I'm doing suburi after a 60 minute taijutsu session. It's worked out quite well so far. The real test, though, will be the ridiculously humid summer months.
